5 out of 5 stars For the juror or attorney who will not speak up 08/08/2019
Reviewer: Kim Stephenson   from Official in North Carolina
The power of this is perfect for the courtroom. I can place it on the furthest counsel table and be able to listen with my headset as well as have a recording. Hopefully I will do less interrupting. This review is based on my setup. I'll give another review after court on Monday. As always the support from Sound Professionals it's stellar!

5 out of 5 stars I can finally hear everything! 00/00/0000
Reviewer: A viewer   from Boston
Wow, this is a great product. I used to struggle to hear in my courtroom, but now I can hear everything that is going on without any problem. The best part is the wireless system - I leave the transmitter up by the bench and I can hear every tiny little whisper that is said, better than if I was standing right there! Highly recommended!!
